WIRE-GLASS.

Specification of Letters Patent.

Patented June 9,119'08.

Application filed August 16, 1906. Serial No. 329,976,

To all whom it may concern:

Be it known that I, ARNO ASHUMAN, of Connellsville, county of Fayette, State of Pennsylvania, have invented an Improvement in Wire-Glass, of which the following is a specification.

My invention has reference to wire glass and consists of certain improvements which are fully set forth in the following specification and shown in the accompanying drawings which form a part thereof.

l The object of my invention is to provide a construction of wire glass which will retain its shape in cases, of intense heat where the glass would soften or become greatlyA crushed. The giving to the wire glass propertiesv of this character, insures it embody-` ing exceptionally desirable re retarding.

qualities.

My invention consists in providing the glass sheet with a wire meshed center embedded in the glass and formed of an hexag- 'onal or open mesh, combined with a seriesof parallel longitudinal straight wires incorporated into the hexagonal or open mesh andA preferably extending through the twisted portions thereof.

My invention will be better understood by reference to the drawings, in which Figure 1 is a plan view of a piece of wire, glass embodying my invention; and Fig. 2. is a transverse sectional elevation of the same.

A is the sheet of glass and has embedded within it a wire meshed sheet B of peculiar construction.V This wire sheet conslsts of a series of wires C O twisted together as at D D to form the usual hexagonal mesh, combined with the series of longitudinal wiresE E which are held in lace by the -twisted portions D D of these exavonal mesh. Imthis manner the longitudinal parallel wires E E are vfirmly tied in place and act as braces for each lhexagonal mesh. They also lie in the direction in which the glass is rolled, namely in the direction of the length of the sheet. The advantage of this Wire center is to make mesh is of such form as to maintainv the inv:tegrity of the area of the sheet, and in those cases where intense heat melts the glass or renders' `it pliable, non-extensibility of the longitudinal v ed parts D wire center prevents the distortion of the sheet and sustains its weight so that it acts as an excellent fire retarder. If the straight wire E were not employed, lit is evident that the softening of the glass would'permit distortion of the hexagonal mesh; but by having these straight parallel Wires E in the metallic center, the softened glass would hang straight up and down upon them and alsobe supported by the hexagonal mesh which is lield from distortion by the said wire E.

It is also evident that While the greatest strength due to the wires E is in the direction of their length, it will nevertheless be seen that their bracing action to the' hexagonal f meshes acts to strengthen the sheet greatly in the direction of its width also. It is evi- .dent that while the longitudinal wires E should divide all of the meshes to obtain`the best results, I do not restrict myself in this respect as the supporting action would be accomplished with a smaller number of such the open mesh of the sheet B wouldmore nearly approximate a diamond mesh. i

Ihave shown the most desirable form and manner of making the metallic center B, but

' it is to be understood that it may bereasonably, varied without departing from the spirit of the invention.

Having ynow described my invention what I claim as new and desire to secure by Letters Patent, is:

l. A sheet of wire glass having a metal center formed of an open hexagonal mesh combined with a series' of paral el straight wires united to the wires forming the hexagonal mesh and dividing said octagonal meshes for supporting the weight'of the glass when held vertically at the top.

2. A sheet of wire glass having a metal center formed ofopen mesh wire combined with parallel wires extendin across theopen arts of the meshes and em edded throughout the full length of the glass.

3. A sheet of wire glass having a metal center formed of open mesh wire combined with parallel wires extending across the open parts of the meshes and joined to the wires orming the open meshes and of a length wires. By shortening the twistequal to thetotal length of the glass sheet. l

4. Asheet of wire glass having a metal center `formed of hexagonal meshes the con-. necting wires of which are twisted together,

eombined with a series of parallel longitudinal Wires dividing the lmeshes. and tied in place by the twisted portions and oompletely embedded in the glass throughout its length. A 1

.5. A sheet of Wire glass having a metal centervreomposed of a series o'I' Wire lportions connected vtogether and diagonally arranged to form an'open mesh, combined With 1on- 10 gitudinal ,parallel straight Wires arranged 'across the open meshes and Wholly embedded in the glass to constitute "part of the metal center.

In testimony of Whch` invention, I have.` hereunto set my hand.
